STOP AND WASTE COCK.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed May 25, 1906. Serial No. 318,644.

To all whom it may concern:

Be it known that I, IVILLIAM E. SMITH, a citizen of the United States ofAmerica, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Stop and asteCocks; and I hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

This invention relates to improvements in stop-and-waste cocks.

The primary object of this invention is to provide a novel andmeritorious simple and durable stop-and-waste cock in which, first, thecomponent parts are readily and conveniently assembled; second, theleversecuring set-screw does not participate in the operative connectionbetween the valveforming plug and the sleeve which surrounds thediametrically larger end of the plug but is arranged wholly externallyof the sleeve and forms a stop arranged to prevent shifting of thesleeve out of operative connection with the plug, and, third, the meansfor limiting the rotary movement of the sleeve and connected plug areformed by two lugs on the sleeve and a corresponding number of lugs onthe body or casing and contained wholly within the sleeve.

IVith this object in view, and to the end of realizing other advantageshereinafter appearing, this invention consists in certain peculiaritiesof construction and combinations of parts hereinafter described andpointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of astopand-waste cock embodying my invention, and in this figure theplug-surrounding sleeve is shown partly in section, and the lever ispartly broken away to reduce the size of the figure. Fig. 2 is aright-hand view relative to Fig. l with the sleeve as well as theplug-operating handle or lever omitted. Fig. 3 is a top plan relative toFig. 1 with the sleeve and plug-operating lever omitted. Fig. A is atransverse section on line 44:, Fig. 1, looking in the directionindicated by the arrow. Fig. 5 is an inner end view of the sleevedetached.

Referring to the drawings, A indicates the body or casing of my improvedstop-andwaste cock, and B represents the valveforming tapering plugwhich is rotatably seated in the valvecasing and has a lateral port 6adapted to establish communication between the ends of the passage-way aformed in and extending through the casing A. One of the side walls ofthe port 7) is provided with a waste-hole Z), and the casing A has awaste-hole a formed at one side of the plug, and the arrangement of theparts is such that when the plug is in position with its waste-hole Z)opposite one end of the pasage-way a the port 5 of the plug shall be incommunication with the hole a in the casing, and when the plug is inposition as shown with its port Z) in line with both ends of thepassage-way a a free passage for water through the casing A is formedand the waste-hole in the plug is closed by the casing. The constructionand operation of the hereinbefore described parts of a stop-and-wastecock are however too well known to require further illustration anddescription in this specification.

The casing A is provided with an annular neck A which surrounds thediametrically larger end-portion of the plug B a suitable distance fromthe outer extremity of the said portion of the said plug, which neck isprovided at its outer end with two diametrically opposite stop-forminglugs 41, which are arranged at opposite sides respectively of and inclose proximity to the plug. The stops at project toward the outerextremity of the diametrically larger end-portion of the plug preferablyabout one-fourth or one-fifth of the distance between the neck A and thesaid extremity, and the said portion of the plug is provided externallycentrally between the said extremity and the neck a with several lugs bwhich are spaced equidistant-1y circumferentially of the plug. The lugs12 project laterally of the plug and are gradually reduced in sizetoward their free extremities. The diametrically larger end-portion ofthe plug is provided with a square hole or socket B which extendsinwardly a suitable distance from the outer extremity of the saidportion of the plug. The socket-forming portion of the plug is providedwith a lateral screwthreaded hole B which extends from the periphery ofthe plug to and connects with the hole B and is shown in dotted lines inFigs. 2 and 3. The screw E shown in Figs. 1 and 4: has itsscrew-threaded shank e screwed into the plug at the hole B and, as shownin dotted lines, Fig. 4, extends into engagement with and somewhat intothe usual square lug K which extends into the hole B in the plug and isformed on the inner end of a handle or lever K employed in turning theplug.

A sleeve 9 surrounds the lug portion of the plug B and extends aroundthe neck A of the casing. Thesleeve g is provided at its outer end andinternally with an annular flange g which snugly embraces the plug atthe outer sides of the lugs 5 The flange g is provided in its inner sidewith as many recesses g as there are lugs 5 formed on the plug, with thesaid recesses snugly engaged by the said lugs. It will be observedtherefore that the flange g is provided with interior portions whichsnugly embrace the lugs 72 on the plug and consequently the sleeve isrevoluble with the rotation of the plug. In other words, the flange 9 isoperatively connected with the plug. The sleeve 9 is provided internallvbetween the outer end of the casing-neck A and the lugs b of the plugwith two laterally and inwardly projecting lugs g arranged diametricallyopposite each other. The lugs g proj ect inwardly between the lugs 64 ofthe neck A but as the lugs g are diametrically opposite obviously one ofthe sleeve-lugs g is arranged between the neek-lugs a at one side of theplug and the other sleeve-lug g is arranged between the neck-lugs a atthe opposite side of the plug. The lugs g of the sleeve 9 thereforecooperate with the lugs 64 of the neck A in limiting the rotary movementof the sleeve and connected plug, and of course the plug is in positionat the one or the other extremity of its rotary movement according asthe sleeve is in position at the one or the other extremity of itsrotary movement.

The lever K is provided with an annular flange II: which overlaps theouter end of the plug.

It will be observed that the lever-securing screw 6 does not participatein limiting the rotary movement of the plug, but that the said screw isarranged wholly outside of the sleeve g, with its shank neXt externallyof the outer side of the flange 9 of the said sleeve, and consequentlyforms a stop for preventing endwise displacement of the sleeve outwardlyout of operative connection with the plug. The screw 6 thereforepositively retains the sleeve in operative connection with the plug, andthe means (necklugs a and sleeve-lugs 9 for limiting the rotation of theplug are contained Wholly within the sleeve.

It will be observed that my improved stop-and-waste cock is simple anddurable in construction and that its component parts are readily andconveniently assembled.

By the construction hereinbefore described, it will be observed that themutually engaging lugs b and recesses g of the plug B, and sleeve 5/respectively, operate substantially as a solid connection between thesleeve and the plug so that there is no liability of the sleeve becomingoperatively disengaged from the plug.

IVhat I claim is In a stop-and-waste cook, a body or casing having aneck A provided with two lugs a projecting longitudinally of andoutwardly from the neck at diametrically opposite sides thereof; atapering plug seated in the casing and having its diametrically largerend-pen tion extending through and a suitable distance beyond the outerend of the said neck, which plug has a socket in the outer end thereofand is provided externally with circumferentially spaced lugs arrangedbetween the aforesaid lug on the casing-neck and the socket-formingportion of the plug; a sleeve 9 surrounding the said neck and plug andprovided at its outer end and internally with an annular flange providedwith a circular opening, the wall of which embraces the plug at theouter sides of the aforesaid lugs of the plug, which flange is providedon its inner side with recesses conforming to and engaged by the lugs ofthe plug, said sleeve being provided internally with two lugs g atdiametrically opposite sides thereof which cooperate with the lugs ofthe aforesaid neck in forming stops for limiting the turning of theplug; a lever for turning the plug, which lever is provided at its innerend witha lug which projects into the socket-forming portion of theplug, and a set-screw screwed into the plug into engagement with the lugof the handle and arranged wholly externally of the sleeve and inposition to prevent endwise displacement of the sleeve out of operativeconnection with the plug.

In testimony whereof, I sign the foregoing specification, in thepresence of two witnesses.
